I fa/e: CT fqyaj BY PM 2 Patented Jan. 1, 1946 HOLDER ATTACHMENT FOR SHARPENING SAFETY RAZOR BLADES Peter C. Rhegas, Detroit, Mich. Application May 23, 1944, Serial No. 536,929

4 Claims.

This invention relates to an improved holder attachment for a razor blade of the wafer-type having a frame reinforcement extending along one edge to hold the blade for sharpening. It is adaptedto hold the blade for use in a sharpening device of the general character described in my co-pending application, Serial Number 529,318 filed April 3, 1944.

Such co-pending. application disclosed a holder adapted to support a wafer-type blade pro-. v vided with a linearly extending slot. Such a blade is typified by the commercial blades of the Gilvlette type. Many wafer-type safety razor blades are not provided with a linearly extending slot and the holder attachment disclosed in this application'is adapted to accommodate these blades. Many wafer-type razor blades are provided with a frame reinforcement extending parallel ,to the cutting edge and along the opposite margin of the blade. The improved holder attachment of this application is designed to accommodate these blades. I

- The blade holder disclosed in my co-pending application above referred to exhibited a base provided with an upright positioning lug adapted to be received through a linear slot in the blade to properly position the blade for sharpening.

.Suchholder was adapted particularly to accommodate blades of the Gillette type referred to above. Unless ablade was provided with such a slot, it was not receivable within the holder described in such co-pending application. The

purpose of the holder attachment of this application is to receive and properly support a blade regardless of whether the blade is provided with such a linearly extending slot or not and the attachment itself is adapted to be secured to the holder disclosed in the co-pending application to properly position the blade thereupon.

The improved holder herein described is simple, inexpensive and adapted to readily receive a blade for use therein or to permit withdrawal of the blade therefrom. The blade is securely held by the attachment for sharpening and the attachment is adapted to be securely positioned upon a holder of the character described in my said co-pending application.

Other objects, advantages and meritorious characteristics of the invention will appear more fully from the following specification, appended claims and accompanying drawing wherein:

Fig. 1 is a plan of a holder of the character shown in my co-pending application, Ser. No. 529,318, having the improved holder attachment of this application positioned thereon.

Fig.2 is a vertical sectional view taken on the line 22 of Fig. 1.

Fig. 3 is a plan of one embodiment of the holder attachment which forms the subject of this application. v

Fig. 4 is a plan of a modified embodiment of the holder attachment of Fi 3.

Fig. 5 is a plan of a second modified embodiment of the holder attachment of Fig. 3.

Fig. 6 is a perspective of a double edged wafertype safety razor blade and a detachable spring clip reinforcement frame adapted to be received over one edge of the blade.

The holder which forms the subject matter of the earlier filed application to which reference has been made hereinabove, is illustrated in Figs. 1 and 2 and comprises a base it) formed of two thicknesses of sheet metal and provided with upright side walls l4 which serve as a handle whereby the holder may be reciprocated. A blade positioning lug l6 projects upwardly from the base as shown in Figs. 1 and 2; In the earlier filed application referred to hereinabove such lug was adapted to be received throughthe linear slot of a safety razor blade to properly position the blade.

This holder was preferably provided with a bale-like. element l8 pivoted at 20 to the side wardly projecting portionof the blade might be depressed evenly throughout its length against afiat honing surface upon which the holder was supported for reciprocation. This construction and the operation thereof was described in the co-pending application hereinabove referred to. a

In the instant application, there is disclosed a holder attachment in the form of a spring clip "general identified as 24, which clip is adapted to receive and securely hold in the proper position a wafer-type blade of the character shown in the drawing. This holder attachment comprises a pair of complementary jaws 26 and 28 held under inherent spring tension toward each other to grip a safety razor blade, such as 30, received therebetween. The razor blade illustrated is provided along one linear margin with a reinforcement frame 32.

The two jaws of the holder are cut away at 34 providing complementary apertures. When a razor blade of the character indicated as 30 in Fig. 2 is properly received between these two jaws tu-fe ejecting ug it: of th hm Eli 13 011; the tprojection of the lug l6 through-the aperture 1M properly positions the attachment "se -that "the;

blade is projected forwardly of the front margin of the holder the proper distance for-accurate sharpening. The blade together with the holder attachment may be tilted to depressthe' beveled cutting edge of the blade against a flat honing surface upon which the blade holder rests. On the other hand, if the blade issu'zhcientlyflerg fble it'ma y be flexed, Without tilting so as to'fbrihg'its het ieat'utjtirieiegige pre erly igaihst t e honing serrate.
